General description The P87LPC779 is a 20-pin single-chip microcontroller designed for low pin count applications demanding high-integration, low cost solutions over a wide range of performance requirements.
A member of the Philips low pin count family, the P87LPC779 offers a four channel, 8-bit A/D converter, two DAC outputs, programmable oscillator configurations for high and low speed crystals or RC operation, wide operating voltage range, programmable port output configurations, selectable Schmitt trigger inputs, LED drive outputs, and a built-in Watchdog timer.
The P87LPC779 is based on an accelerated 80C51 processor architecture that executes instructions at twice the rate of standard 80C51 devices.
